Added new magic school: Occult 'Hereticism', available to Hell Knights, Corrupted Priests and Adventurers (any race, but note that 'Blood Sacrifice' spell to turn yourself into a Bloodthirster will only be available to Hell Knights and Corrupted Priests). Use /sac command to check Blood Sacrifice availability. If you aren't sure what a Bloodthirster looks like, here you can see one (on the receiving end..) https://www.youtube.com/watch?v=aKHsj5y8UL8

Dual-wielding a NEVER_BLOW weapon ('of Nothingness') and a normal weapon will still allow attacking (with the normal weapon).

Inscriptions added: '\\' will append to an existing inscription, '@@' will inscribe an item with all its special powers. '@@' must always stand at the beginning of an inscription, you can add further text after it if you like, which will then be appended.

Various serpents and nagas had water resistance added.

New command added: /applaud.

Running around in a form that has erratical movement will no longer place you into terrain that prevents running nor change the worldmap sector accidentally.
